About: Island algorithm

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

The island algorithm is an algorithm for performing inference on hidden Markov models, or their generalization, dynamic Bayesian networks.It calculates the marginal distribution for each unobserved node, conditional on any observed nodes.

Property Value
dbo:abstract
  • The island algorithm is an algorithm for performing inference on hidden Markov models, or their generalization, dynamic Bayesian networks.It calculates the marginal distribution for each unobserved node, conditional on any observed nodes. The island algorithm is a modification of belief propagation. It trades smaller memory usage for longer running time: while belief propagation takes O(n) time and O(n) memory, the island algorithm takes O(n log n) time and O(log n) memory. On a computer with an unlimited number of processors, this can be reduced to O(n) total time, while still taking only O(log n) memory. (en)
